My gg-grandmother was Maria de los Angeles (aka "Angela")Cifuentes, baptized 4 october 1841 in Panuco, Zacatecas and m. to Feliciano Reyes. She was the d/o of Jose Maria Sifuentes and Concepcion Flores, who had at least one other child: Sutimio Cifuentes, who m. Maria ___ Bernales and had a son, Jose de la Cruz Cifuentes, baptized 9 May 1861.
Jose Maria Sifuentes was the s/o Pedro Cifuentes and San Juana Palacios, who had at least one other son, Asencion Cifuentes, who m. Fomada Ruiz and had at least one son, Aniseto Cifuentes, baptized 21 march 1862, in Zacatecas.
I do not have dates and places of birth except for Maria/Angela and her cousins, so it is possible their parents came from Coahuila. Incidentally, my father, Carlos Cervantes, was b. 4 Nov 1913 in El Lucero, Coahuila.
Please let me know if any of these names form a connection.
